Description

Technical Field

[0001] The utility model relates to the technical field of granule counting machines, and more specifically, to a double plug door. Background Art

[0002] A granule counting machine is a machine applicable to industries such as pharmaceuticals, hospitals, and food, and is used for counting medicines or foods such as capsules, tablets, and granules. This machine is small in volume, light in weight, accurate in counting, and simple in operation. The contact surfaces of the counted items are all made of stainless steel, and it is an ideal special equipment for counting bottled, bagged, and canned products in relevant industries.

[0003] The existing granule counting machine has a large occupied space at the material discharge port. Both the double-door structure and the flap door structure will occupy a large height space, while the single plug door structure takes too long for the door to open and close back and forth, which is likely to cause waste of time in the long-term use and increase the processing time cost. Therefore, it is particularly important to have a double plug door device that can reduce the space occupancy rate and improve the door closing efficiency. In view of this, we propose a double plug door. Summary of the Utility Model

[0006] The utility model shortens the door opening and closing time by half, reduces the time cost, improves the material discharge rate, and uses two obliquely arranged plug door panels to reduce the space occupancy rate and optimize the effect of intercepting and discharging materials.

[0007] Preferably, the inside of the material discharge bin is an open cavity, and wave grooves are opened at the lower ends of the two side walls corresponding to the two plug door panels.

[0009] Preferably, the bump includes a protruding portion and a bending portion. The protruding portion is a vertically elliptical arc-shaped protrusion, and the bumps are connected by the bending portion to form a slot.

[0010] Preferably, oil pressure buffers A are arranged on both of the two plug door cylinders, and an oil pressure buffer B is fixedly connected to the position of the blanking bin relative to the two side cylinder support plates.

[0011] Preferably, the buffer end of the oil pressure buffer B abuts against one side of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] As Figures 1 to 4As shown in the figure, a double plug door involved in the utility model includes a blanking bin 1. A cylinder support plate 2 is arranged on the surface of the blanking bin 1. The cylinder support plate 2 is arranged obliquely on both sides of the blanking bin 1. The upper end surfaces of the two cylinder support plates 2 are fixedly connected with plug door cylinders 3 respectively. The telescopic ends of the two plug door cylinders 3 are fixedly connected with connecting plates. One side of the two connecting plates facing each other is fixedly connected with a plug door panel 4. The surface of the plug door panel 4 is slidably connected to the upper surface of the cylinder support plate 2 at the same time. Oil pressure buffers A8 are arranged on both of the two plug door cylinders 3. The blanking bin 1 is fixedly connected with an oil pressure buffer B9 at a position relative to the two cylinder support plates 2 on both sides. The buffer end of the oil pressure buffer B9 abuts against one side of the connecting plate. By symmetrically arranging two plug door panels 4 at the blanking outlet of the blanking bin 1 to move synchronously, the opening and closing time of the single door is shortened by half, the time cost is reduced, the blanking rate is improved, and the two obliquely arranged plug door panels 4 can reduce the space occupancy rate and optimize the effect of intercepting and discharging materials.

[0022] In the embodiment of the utility model, the inside of the blanking bin 1 is provided as a through cavity. Wave grooves 5 are opened at the lower ends of the two side walls corresponding to the two plug door panels 4. The surface of the plug door panel 4 is slidably connected to the lower surface of the wave groove 5 through bumps 6. The bumps 6 are fixedly connected to the plug door panel 4 in an equidistant vertical shape. The bump 6 includes a protruding part 61 and a bending part 62. The protruding part 61 is a vertically elliptical arc-shaped protrusion. The bumps 6 are connected by the bending part 62 to form an embedding groove 7. By arranging the bumps 6, the protruding part 61 and the bending part 62 can be used to contact the surface of the wave groove 5, so that the biting degree between the plug door panel 4 and the wave groove 5 is closer, the sealing effect is better when the plug door panel 4 moves, and the sealing performance of the plug door panel 4 when opening and closing the door and the connection tightness with the blanking bin 1 are further improved.

[0023] Working principle: This embodiment provides a double plug door. When in use, during blanking, first, the two plug door cylinders 3 on both sides contract synchronously, thereby driving the two plug door panels 4 to move in opposite directions in the wave grooves 5. By symmetrically arranging the two plug door panels 4, when opening the material conveying port of the blanking bin 1, the opening time can be shortened by half. When it is necessary to close the blanking bin 1, the two plug door cylinders 3 on both sides can stretch synchronously, thereby driving the two plug door panels 4 to move in opposite directions in the wave grooves 5, so that the two plug door panels 4 are in contact with each other, and the protruding part 61 and the bending part 62 are used to increase the contact points with the wave groove 5, so that the plug door panel 4 increases the embedding and biting point degree with the wave groove 5 when moving, improves the connection tightness and sealing performance between the two, and the oil pressure buffer A8 and the oil pressure buffer B9 are respectively arranged on the plug door cylinder 3 and the movement path of the plug door panel 4, so that the plug door panel 4 can be buffered when in the closed state, and the noise generated by the collision between the two plug door panels 4 is reduced.

[0024] The embodiments disclosed in the present utility model are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
